STOOL.

i ,sottesa Specification of Letters Patent. Patented Nov, 14, 1916,

Application led April 2, 1915. Serial No. 18,707.

This invention relates to stools or seats of the class usually known as camp stools, and the object thereof is to provide an improved device of this class which is com- '1' posed of separate detachably connected t and easily set up for use whenever` and wherever desired, and which will also be suiiiciently strong to support any necessary weight and will not easily get out of order or frequently need repair.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a. part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a perspective side view of my improved stool; Fig. 2 a partial section on the line 2-2 of Fig. 1; Fig. 3 a partial longitudinal section through one of the legs and on the line 3 3 of Fig. 2; Fig. 4 a section on the line 4-1 of Fig. f1; and, Fig. 5 a partial section on the line 5-5 of Fig. a,

My improved stool is made in the form of a tripod and is composed of a plurality of legs a, preferably three in number, a

head b with which the legs a are connected and a seat c connected with the head t).

The head Z) is approximately triangular in form, or comprises a central body portion having three equally spacedk arms b2 to which the legs a are hinged as shown in Figs. 1 and 3. Tn this operation the arms b2 are provided in their under sides and outer ends with slots 3, and the legs a with blocks a2 having tongues a3 which fit in said slots. Screws or bolts t4 are passed through the arms 62 and tongues a3 for connecting the legs with the head b and forming hinges on which said legs are free to swing radially.

The legs a are composed of telescopic members a* and a5 and the blocks a2 are secured in the upper ends of the outer partsl a4 of said legs. Placed in the upper ends of the inner parts a5 are loop-shaped or U-shaped springs a, the end portions of which are provided with plugs a7 movable outwardly and inwardly through corresponding holes as in both the inner and thev outer parts at and a5 of said legs, while the lower ends of the parts a5 of said legs are provided with knobs or heads a9.

In the accompanying drawing, Figs. 1 and 8, the-legs a are telescoped to their fullest extent and the plugs a7 are operating in the upper holes as, and by forcing said plugs inwardly by means of the thumb and finger the parts a5 of the legs may be drawn out until said plugs will operate in the lower holes a8. Said legs will then be extended or lengthened to the fullest extent. It will be understood that the part av4 of the legs may be provided with any preferred number of the holes as and the height of the stool may thus be regulated to any desired extent.

Beneath the head I) and hinged to one of the legs a as shown at d is a lock block cl2 which is approximately triangular in form, or provided with three projecting members corresponding with the legs a, one of which is provided with a downwardly directed lug d3. then the stool is in position for use,

as shown in Fig. 1, the lock block d2 is raised into the position shown in said figure, and operates to lock or hold the legs in operative position by a spring controlled pin (Z4 .passing through the top portion of one of the legs a and provided at its outer end with a milled head d5. TNithinvthe said leg is a spiral spring cl which normally forces the pin alt inwardly into operative position so as to secure the lock block Z2 in operative position, and when it is desired to fold the legs a together the pin d4 is drawn outwardly and the lock block d2 dropped down'- wardly'between said legs.

The seat c is preferably circular in form and consists of three parts c2, each of which is composed of a central block member c3 and a bottom plate c4, the central block member 03 being upholstered as shown at c5, in the form of construction shown, and the bottom plate member being secured to the central block member by screws 06. The

separate parts 02 of the seat are hinged together as shown at c", and the bottom plate c* of the central part of the seat is provided with a central pin S on which .is mounted an oblong loclt plate e which is rotatable `Von said pin, and the pin CS is adapted to `end thereof enters the central pin o8 of the seat as shown in said ligure. In this position of the parts the seat is locked to the head, but whenever desired the pin may be drawn outwardly and the seat detached from VVthe head 7), as will be readily understood,

and the separate parts of the seat may be 'folded up, or folded together, but in this operation the plate emust be turned around into the position shown in dotted lines 1n Tn'- rig. it.. I

ln order to operate the plate c, as above -'described and as shown in Fig. et, said plate must be longitudinally movable on the pin to a. slight extent, and said pin is provided on its opposite sides with stops or lugs g to limit rthe movement of said plate thereon. The head b -is provided on the opposite sides of the central socket or recess c with recesses g2 to receive said stops or lugs g when the seat is attached to the head Z). The end of the lock pin CS is also provided in its opposite sides with beveled recesses z. to receive the inner end of the loclr pin j', when the seat is forced downwardly into position, whereby the lock pin is forced outwardlyY by the operation of forcing the seat downwardly' in position, and then inwardly by the spring y' which operates the lock pin f in one direction.

When the seat c, or its separate parts are made thick, as shown in Figs. l and 5, they cannot be compactly folded together, but my invention is not limited to the construction of theseat, or the separate parts thereof as herein shown and described, and said separate parts may be made thin and of any suitable material and the hinges so formed that when the seat is detached from the head, thel separate parts thereof may be compactly folded together. Vith my improvement the legs a, or the separate parts Copies of'this patent may be' obtained for thereof, may be telescoped into the shortest possiblev space and folded compactly together, Vand the seat may be detached from tae head and its separate parts folded oompactly together, and in this way the entire device may be carried in a small package, or in a handbag.

ln order to insure the operation of the parts of the telescopic legs as herein shown and described and of the locking springs ft therein, said legs or the separate parts thereof must be rectangular in form in cross section, or of such form as to prevent the rotation of the inner parts in the outer parts.

lhile I have shown and described the preferred details of the various parts of my improved stool, my invention is not limited thereto, and changes therein and modifications thereof may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what c l claim as vnew and desire to secure by Letters Patent isl. ln a stool of the class described, a head and a detachable seat connected therewith. said seat being composed of a central part and side portions hinged thereto, and the central part being provided with a projecting pin by which it is connected with the head and on which is mounted a lock plate which is movable longitudinally of said pin and rotatable thereon.

2. In a stool of the class described, a head, a detachable seat connected therewith, legs pivoted to said head, said seat being provided 'with a projecting pin by which it is connected with said head, a lock device hinged to one of said legs and adapted to hold said legs in their operative position, and spring-controlled means connected with one of the other of said legs for supporting said lock device in its operative position.

ln testimony that I claim tlie'-foregoi11g i as my invention l have signed my name, in

presence of the subscribing witnesses, this lst day of April, 191,5.
